Fermentative digestion of food in the colobus monkey, Colobus, polykomos.
(Department of Veterinary Anatomy and Physiology, University of Nairobi, 1976-04)Fermentation of leafy food occurs in the enlarged saccus gastricus of the colobus monkey with the formation of volatile fatty acid, as in the rumen of ruminant animals. About half of the digestible organic matter and ... -
Respiratory properties of blood in awake and estivating lungfish, Protopterus amphibius.
(Department of Veterinary Anatomy and Physiology, University of Nairobi, 1976-09)Blood respiratory properties have been studied in awake and estivating African lungfish, Protopterus amphibius. Fish had been estivating 28-30 months when blood was sampled. Hematocrit, O2 capacity and blood hemoglobin ... -
Importance of air and water breathing in relation to size of the African lungfish Protopterus amphibius Peters.
(Department of Veterinary Anatomy and Physiology, University of Nairobi, 1976)1. Oxygen uptakes from air and water have been measured in relation to weight of the African lungfish Protopterus amphibius Peters. 2. Combined O2 uptake from air and water ranged from 60 ml O2 kg-1 h-1 STPD, in a 3-7 g ... -
Blood respiratory properties in the naked mole rat Heterocephalus glaber, a mammal of low body temperature.
(Department of Veterinary Anatomy and Physiology, University of Nairobi, 1976-12)Respiratory properties of whole blood and Hb solutions have been studied in Heterocephalus glaber, a fossorial rodent, having a low body temperature (30.0-32.0 degrees C) and poor thermoregulatory ability. For comparison ... -
Oxygen-binding properties of hemoglobins from estivating and active African lungfish.
(Department of Veterinary Anatomy and Physiology, University of Nairobi, 1991-01)he oxygen-binding characteristics and the multiplicity of the stripped hemoglobiin from active lungfish Protopterus amphibius, are the same as in specimens that have been estivating for about 30 months, showing that ... -
Tissue metabolism and enzyme activities in the rodent Heterocephalus glaber, a poor temperature regulator.
(Department of Veterinary Anatomy and Physiology, University of Nairobi, 1977)1. Tissue oxygen uptake and enzyme activities were investigated in the naked mole rat, Heterocephalus glaber, a mammal notable for its low body temperature and metabolism and poor temperature regulating ability. 2. Q10 for ... -
Cyclic changes in the osmolality and electrolyte composition in the gastrointestinal tract of the rock hyrax.
(Department of Veterinary Anatomy and Physiology, University of Nairobi, 1978-06)The rock hyrax has been shown to have a very unusual and complex digestive tract. The gastrointestinal tract is comparable to that of the simple and complex stomach of mammals as well as to that of birds. Determinations ... -
Nasal heat exchange in the giraffe and other large mammals.
(North Holland PublishingDepartment of Veterinary Anatomy and Physiology, University of Nairobi, 1979-08)The respiratory air of the giraffe is exhaled at temperatures substantially below body core temperature. As a consequence, the water content of the exhaled air is reduced to levels below that in pulmonary air, resulting ... -
Energy metabolism and heart rate during treadmill exercise in the Marabou stork.
(Department of Veterinary Anatomy and Physiology, University of Nairobi, 1980-09)Oxygen consumption (VO2), heart rate, body temperature, and stride frequency were measured in Marabou storks walking on a treadmill at a range of speeds and gradients. VO2 was linearly related to speed at gradients up to ... -
Gastrointestinal osmolality electrolyte and organic acid composition in five species of East African herbivorous mammals.
(Department of Veterinary Anatomy and Physiology, University of Nairobi, 1980-10)Inherent differences observed in ionic composition of gastrointestinal contents due to diet, feeding regimen and (or) site along the length of the digestive tract were controlled so that a clearer understanding of ... -
An ultrastructural and histochemical study of the axial musculature in the African lungfish.
(Springer-Verlag.Department of Veterinary Anatomy and Physiology, University of Nairobi, 1981)Red, intermediate, and white axial muscle fibres of African lungfish were studied using histochemical techniques and electron microscopy. Gross dissection revealed the presence of a small wedge of red coloured muscle along ... -
Design of the mammalian respiratory system. II. Measuring maximum aerobic capacity.
(Department of Veterinary Anatomy and Physiology, University of Nairobi, 1981-04)We describe a simple and reproducible procedure for measuring maximal O2 consumption (Vo2max) that can be used for mammals spanning a wide range of body mass (Mb). Vo2 of trained animals was measured as a function of speed ... -
Design of the mammalian respiratory system. IX. Functional and structural limits for oxygen flow.
(Department of Veterinary Anatomy and Physiology, University of Nairobi, 1981-04)This paper presents the synthesis and interpretation of a series of correlated studies of the mammalian respiratory system--measurements of maximal rate of O2 consumption, the lung's diffusing capacity, the mitochondrial ... -
Design of the mammalian respiratory system. III Scaling maximum aerobic capacity to body mass: wild and domestic mammals.
(Department of Veterinary Anatomy and Physiology, University of Nairobi, 1981-04)The purpose of this study was to determine whether the maximal rate of oxygen consumption (Vo2max) is scaled proportionally to Mb1.0, as the diffusing capacity of the lung, or proportionally to Mb0.75, as the standardized ... -
Design of the mammalian respiratory system. V. Scaling morphometric pulmonary diffusing capacity to body mass: wild and domestic mammals.
(Department of Veterinary Anatomy and Physiology, University of Nairobi, 1981-04)This paper utilizes a comparative approach to establish the relationship between morphometric diffusing capacity for oxygen (DLo2) and maximal oxygen consumption (Vo2max). DLo2 and Vo2max were determined on the same 21 ... -
The relationship between rate of oxygen consumption, heart rate and thermal conductance of the dik-dik antelope (Rhynchotragus kirkii) at various ambient temperatures.
(Department of Veterinary Anatomy and Physiology, University of Nairobi, 1982)1. The extent of cardiovascular adjustments to heat and cold were investigated between ambient temperatures of 5 and 45 degrees C by measuring conductance and the rates of oxygen consumption and heart beats. 2. Minimum ... -
Energetics and mechanics of terrestrial locomotion. I. Metabolic energy consumption as a function of speed and body size in birds and mammals.
(Department of Veterinary Anatomy and Physiology, University of Nairobi, 1982-04)This series of four papers investigates the link between the energetics and the mechanics of terrestrial locomotion. Two experimental variables are used throughout the study: speed and body size. Mass-specific metabolic ... -
Respiration and metabolism in the giraffe.
(Department of Veterinary Anatomy and Physiology, University of Nairobi, 1982-11)Measurements have been made on respiration of three resting unstressed adult giraffe under normal conditions. Tracheal dimensions and body dimensions have also been measured in a large number of giraffe and other mammals. ... -
Molar proportions of volatile fatty acids in the gastrointestinal tract of East African wild ruminants.
